Sixteen people were shot, two fatally, in Chicago from Thursday to early Friday, including a shooting that wounded five people in the South Shore neighborhood, according to police.

One man was killed and another was critically injured about 2:55 a.m. Friday in the 500 block of West Iowa Street in the Cabrini-Green rowhouses, according to police. Someone shot a 31-year-old man multiple times in the face, according to police. He was pronounced dead at the scene.

A 34-year-old man was shot multiple times in the abdomen. He was in critical condition at Northwestern Memorial Hospital.

Police do not yet know what led to the shooting. No one was in custody.

In the South Shore neighborhood late Thursday, a shooting killed an 18-year-old man and wounded four other people in the 2000 block of East 71st Street.

Just before 10:40 p.m. Thursday, someone in a tan minivan opened fire and hit the 18-year-old, Zaire Benjamin, in the head. He was taken to Northwestern Memorial Hospital, where he was pronounced dead.

Benjamin lived in the 6800 block of S. Paxton Avenue, according to the medical acaminer. His family members declined to comment.

A 19-year-old man was shot in the abdomen and the groin during the attack. He was in critical condition at Northwestern Memorial Hospital.

Two 21-year-old men took themselves to Jackson Park Hospital, where their conditions were stabilized. One had been shot in the left leg and back, and the other 21-year-old man was hit in the buttocks.

A fifth man, another 18-year-old man, was shot in the left wrist. His condition was stabilized at Trinity Hospital.

On 71st Street, people gathered across the street from the crime scene and watched as detectives focused on an alley near a sandwich shop.

Among those huddled was a couple who had been delivering food as part of UberEats when they heard gunshots. The woman asked to be identified as Janet and the man did not want to be identified.

"It was so close, that you can feel it in your ears," Janet said. "There's no way for us to hide, it's like when is this going to stop?"

Another woman, who did not want to be identified, was passing through and stopped to get a closer look at the crime scene. She moved away from the neighborhood a couple of months ago because of the violence.

"This is every day," she said.

On the West Side, another shoting fatal attack happened about 2:30 p.m. at Chicago and Lawndale avenues in the Humboldt Park neighborhood, according to a Chicago Fire Department spokesman.

A 19-year-old man was walking when a gunman came up and shot him in the face, police said. He remained in critical condition at Stroger Hospital.

Police earlier said the man was dead on the scene.

Fire Department personnel responded to assist police with a SWAT operation because someone apparently was holed up inside a building nearby in the 500 block of North Hamlin Avenue.

Police were led there after witnesses told officers a possible suspect in the homicide had retreated into that home, said Officer Michelle Tannehill, a police spokeswoman.

The SWAT operation was canceled about 7 p.m. after police, who were given consent to search the home, did not find anyone inside, Tannehill said.

CTA bus veers off road after shooting

Two people were shot and a third was hit by flying glass after a shooting in the Park Manor neighborhood that caused a CTA bus to veer off the road Thursday evening.

The victims were on foot in the 600 block of East 71st Street about 7:15 p.m. when an assailant got out of a dark-colored SUV and fired, police said.

A 48-year-old woman was shot in the head, and a 40-year-old man was shot in the back. They were both taken Advocate Christ Medical Center in Oak Lawn in serious condition, police said.

A third victim, a 33-year-old woman, was hit by flying glass and suffered a laceration to her hand, police said. She was taken to Jackson Park hospital in good condition.

Officials did not immediately say how the 33-year-old woman was injured by the glass but as of about 9 p.m. a CTA 71st Street bus that had apparently tried to swerve away from the shooting remained at the scene after hopping a curb and traveling onto a sidewalk, where it appeared to have narrowly missed crashing into a black, wrought-iron fence.

A CTA employee at the scene said the westbound bus didn't appear to be badly damaged in the shooting, but it struck the front bumper of a parked vehicle as it crossed over into the opposite lanes of traffic and jumped the curb.

The entire intersection of 71st Street and St. Lawrence Avenue had been cordoned off with red and yellow tape that kept several bystanders away from the scene and the nearly two dozen shell casings bunched at the northeast corner of the intersection.

After receiving a "hysterical" call that his 47-year-old mother-in-law was wounded in the shooting, Dwight Rogers, of the Roseland neighborhood, said he rushed to her home to check on children before walking to the scene in hopes of finding out what happened.

"I was surprised. I said, she had to be walking from the store, because she's a gentle person, not into any of that," he said. "Just wrong place wrong time,’’ Rogers said.

Triple shooting in Back of the Yards

About 4:30 p.m. on the South Side, two women and a man were shot in the 5100 block of South Loomis Street in the Back of the Yards neighborhood, police said. Earlier, police said it happened in the 5100 block of South Elizabeth Street.

They were walking through an alley when someone in a red vehicle opened fire, hitting a 22-year-old woman in the back, a 24-year-old woman in the abdomen and a 25-year-old man in the chest, police said.

The 22-year-old's condition was good while the conditions of the other two had been stabilized.

A Chicago police SUV was parked due south of 51st and Elizabeth streets, where a single evidence marker sat atop a shell casing.

A man, who declined to give his name, said he was sitting outside of his garage less than a block away when he heard a ruckus and poked his head down the alley to see the aftermath.

"I didn't know it was shots until I saw people running and making commotion," he said. "It's kind of rough. They can't seem to put a hold on this (violence)."

The man, who's lived in the neighborhood since 1990, said he's reached his breaking point with what he called the rampant gun violence, and Thursday's shooting bolstered his decision to leave the city where he once laid roots.

"I'm gonna get up out of here," he said, leaning forward in his folding chair. "I'm gonna leave here. I can't stay. It ain't changing. I sit out here all day and say, 'You hear about the shooting and you never know when it'll come right to your door.' And there it is! I could've been out on my porch and got shot."

The alley where the shooting happened runs between a religious ministry and a large community garden. However, the scene remained mostly silent about 6 p.m., and except for traffic noise from 51st Street, it was devoid of gawkers or bystanders.

"It's a triple shooting, but it's so quiet and empty," said crisis responder Donovan Price, who was also there. "That's because it's not a big deal in Chicago, unfortunately."

In other shootings:

-- About 1:10 a.m. Friday on the South Side, someone shot a 28-year-old man in the leg in the 4000 block of South Princeton Avenue in the Fuller Park neighborhood, police said. His condition was stabilized at Mercy Hospital.

-- In the West Side's Humboldt Park neighborhood, a 19-year-old man was standing in the 800 block of North Springfield Avenue about 11:45 p.m. Thursday when someone shot him in the left leg, according to police. He took himself to Stroger Hospital, where his condition was stabilized.

-- About 11:25 p.m. on the West Side, an 18-year-old man was shot in the left hand while in a parked car in the 2600 block of West Adams Street, police said. Someone in a sedan pulled up next to the car and someone opened fire, striking him in the hand. He took himself to Mount Sinai Hospital, where his condition was stabilized.
